m16480	Evaluation of Video Signature Based on Tomography	Sebastian Possos

The main activity during the week was the evaluation of the results of Core Experiments. Unfortunately, there was some inconsistency due to the late detection of cases where the used video decoder crashed and produced black frames with an information message, which in one class of experiments could bias the results. Some of the experiments needed to be re-done, such that results partially arrived only after the official document update deadline. Even though, only M16414 and M16430 were able to provide complete CE results during the meeting; other parties were not able to finalize their computations (for which the flaw described above did not play any role). From the results available, better performance was observed from the contribution M16430. In fact, this is a merging of two original CfP proposals, using a ternary frame signature from regions of interest, from which “words” and "bags of words" (histograms) of the signature values are constructed. It was therefore decided to adopt this method for WD, and include the related matching procedures in the XM. As in the case of Image Signature Descriptor, the method is closely coupled to the underlying image processing algorithm, such that extraction needs to be specified as a normative part. It is further recommended to shift the issuing of PDAM4 into the July meeting, which still will allow to produce FPDAM by October.

Software, conformance and matching tools for the Image Signature Descriptor were also progressed as the respective FPDAM / DAM texts. With regard to the conformance, it is raised in one NB comment that the aspect of normative extraction method should have implication on the conformance definition (e.g. allowing a certain margin of divergence when extracting the descriptor from image data), which will be considered in the FPDAM text.
